After resolution with corticosteroids, treatment was switched to afatinib. This study highlights the heterogeneous approaches to OILI and the potential feasibility of rechallenge in selected patients. Given the expanding osimertinib use for early and advanced stage NSCLC, further research is warranted to refine treatment decisions and optimize patient safety.

Preoperative ctDNA detection and pathological venous invasion provide complementary prognostic information, and venous invasion is an independent predictor of recurrence risk in EGFR-mutated NSCLC. Combined assessment may refine postoperative risk stratification and inform perioperative management.

PRO results indicate that the clinical benefits of adding amivantamab to chemotherapy were achieved without compromising health-related QoL. Amivantamab-chemotherapy prolonged TTSP versus chemotherapy alone.

In the first-line setting, targeted therapy and SSAs were associated with longer PFS than chemotherapy, with surufatinib and lanreotide showing favorable disease control. SDHx pathogenic variant status did not show a clear association with response to TKIs or temozolomide, underscoring the need for validation in larger cohorts.

Targeting this axis with combinatorial inhibitors exerted synergistic anti-tumor effects, suppressing proliferation and migration in osimertinib-resistant models. In conclusion, concurrent inhibition of EGFR and FGFR1/STAT3/PLK1 signaling pathways provides a promising therapeutic strategy for NSCLC patients with EGFR mutations, enhancing efficacy and overcoming resistance.

Adding upfront SRS to osimertinib did not significantly improve 12-month ic-PFS in EGFR mutant NSCLC with BM. This represents the first randomised evidence supporting the use of osimertinib monotherapy as upfront therapy in minimally symptomatic patients with low burden BM.

With no other treatment options, palliative osimertinib rechallenge led to rapid neurological improvement and radiological response, without ILD recurrence. This case highlights the potential of carefully monitored osimertinib rechallenge for symptomatic relief in exceptional cases.

The results showed that SPP1 regulates cancer stem cells (CSCs) by interacting with CD44, thereby generating osimertinib resistance. These findings provide a basis for clinical research.
